President Trump highlighted the heroism of the first responders and survivors who helped victims of a massive shooting in Las Vegas on Sunday evening, telling a group gathered at police headquarters in Las Vegas on Wednesday that the country is grieving together for the 59 people who died in the attack.

"America is truly a nation in mourning," Trump said during remarks at the Las Vegas Police Department facility.

"In the months ahead, we will all have to wrestle with the horror of what has unfolded this week, but we will struggle through it together. We will endure the pain together, and we will overcome this together as Americans."

Trump cited several stories of police officers or victims who helped people escape the rainstorm of bullets that 64-year-old Stephen Paddock sprayed down on the audience at a country music festival from his perch on the 32nd floor of the nearby Mandalay Bay Resort and Casino. More than 500 concertgoers sustained injuries from gunfire or from attempting to escape the shots in the thick crowd.

"Words cannot describe the bravery the whole world witnessed on Sunday night," Trump said. "The example of those whose final act was to sacrifice themselves for those they loved should inspire all of us to show more love every day for the people who grace our lives."

Earlier Wednesday, the president and first lady visited with victims and their families at a Las Vegas hospital.
